Yes, the Nvidia product names are misleading and they should put a
stop to it. You aren't the first to raise this issue. When the 8400GS
(G98 models) first came out they all had 400MHz DDR2 memory with a few
that had 500MHz (including the ref. board). I would have noticed this
sooner if the store you purchased your card from had the specs listed
correctly. If you go to newegg and the manufacturer's website it
clearly states 532MHz effective (266MHz). That's ~33% less memory
bandwidth.

No worries, the 210 will easily do Temporal 2X.

Good luck.
